Efficient debris separation for gold washing - Grid bottom design helps sort out large, unusable contaminants quickly, reducing manual sifting and speeding up the washing process. Power-free operation with universal compatibility - Unrestricted use: requires only a water source, no electricity or power supply needed. Simple setup and reliable performance in remote locations. High visibility and ease of use - Green body design enhances the visibility of gold nuggets, making identification easier and handling straightforward. Designed for off-grid and remote locations - Suitable for use in mountain areas, rivers, and streams where electricity and transport may be limited or unavailable. Use scenarios - Remote mountain stream prospecting: carry the device into the field, use it in flowing water to separate debris, and collect the gold-bearing concentrate with minimal effort. - Riverside field surveys: wash and rinse material near the water source; the grid bottom accelerates cleanup while the green body helps spot gold early in the process. - Off-grid hobby mining trips: pack light for weekend trips to streams; no power required, quick setup, and easy operation for quick results.
